I am new to XMPP. For a whole day I am stuck in connecting to my XMPP server (Openfire version 3.9.3) from Java. I am using the Smack (version 4.0.7) library. Here is simple code...
ConnectionConfiguration config =new ConnectionConfiguration("servername",5223);
XMPPTCPConnection connection = new XMPPTCPConnection(config);
// Connect to the server
try {
connection.connect();
connection.login("username", "password");
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();
} catch (SmackException e) {
e.printStackTrace();
}
But when I run this code this error is showing ...
org.jivesoftware.smack.SmackException$NoResponseException
at org.jivesoftware.smack.XMPPConnection.throwConnectionExceptionOrNoResponse(XMPPConnection.java:548)
at org.jivesoftware.smack.tcp.XMPPTCPConnection.throwConnectionExceptionOrNoResponse(XMPPTCPConnection.java:867)

There may be a silly mistake and easy solution. I googled but somehow I am not getting the right solution.
public void connectAndLogin( {
connect();
login();
}
private void connect() {
/**
* Set server configuration
*
* connect to server
*/
setConfiguration();
try {
getConnection().connect();
} catch (XMPPException e) {
e.printStackTrace();
setConnection(null);
}
}
private void setConfiguration() {
ConnectionConfiguration config = new ConnectionConfiguration(Constants.IP);
SmackConfiguration.setPacketReplyTimeout(Constants.PACKET_TIME_OUT);
System.out.println(SmackConfiguration.getVersion());
config.setRosterLoadedAtLogin(false);
// config.setCompressionEnabled(true);
config.setVerifyChainEnabled(false);
config.setReconnectionAllowed(true);
config.setSASLAuthenticationEnabled(false);
config.setSecurityMode(SecurityMode.disabled);
config.setDebuggerEnabled(false);
connection = new XMPPConnection(config);
}
private void login() {
if(getConnection()!=null){
String USER_NAME="";
String PASSWORD="";
try {
getConnection().login(USER_NAME,PASSWORD, Constants.RESOURCE);
} catch (Exception e) {
e.printStackTrace();
}
}
}
尝试使用端口5222而不是5223.这是旧的SSL方式,通常不再使用。
